Drawings of the Grasshopper aircraft emerged.
The Aviation Institute didn't take any pause and immediately started building it. This time, they were full of confidence.
Although the dual-powered plane failed and crashed. But will the Grasshopper also fail
No, absolutely not.
Although the Grasshopper is compact, its stability will be very powerful. According to estimates, even if the Grasshopper's engine stalls in the air, the aircraft will glide to the ground smoothly and there will be no crash at all.
Especially after the last incident of broken wings. The Aviation Academy has an obsessive pursuit of the strength of wings.
The overall frame of the aircraft has been redesigned, using the concept of keel and mortise and tenon technology commonly used in the shipbuilding industry.
There is not a single screw used in the entire Grasshopper, and everything is connected by mortise and tenon. The skeleton of the keel is directly a double-layer defense method. The first layer is a mortise and tenon connection, and the second layer is welding.
Regarding the sturdiness, the Aviation Institute has become obsessed with it. It seems that after two plane crashes, everyone has a kind of obsessive-compulsive disorder.
Even if the special plane falls apart in the sky, its wings must not be broken.
When the finished products of the Grasshopper's wings were released, everyone used the most stringent and violent methods for testing. A group of people jumped on it and stepped on it. No matter how hard you step on it, the wings just flap up and down, but they don't break. Has great flexibility.
Of course, some weight is also sacrificed.
But not much. These weights have little impact on the overall situation.
Because the Grasshopper is too small...
According to some students, this Grasshopper can actually be driven by a two-stroke engine. The power of the radial engine is simply wasted on this.
But after failing twice before, everyone was a little scared. When a lion fights a rabbit, it’s better to use all your strength.
Li Zhen passed by the Aviation Academy and took a glance, and saw that the skeleton of the plane had appeared. Everyone is filling in the skeleton.
After taking a look at the model, Li Zhen didn't care too much and wasn't curious about it.
This is the simplest model. With the aviation institute's technology, they can build it with their eyes closed. If I'm not kidding, a small aircraft like the Grasshopper is bi-winged. They can put it together for you without drawings.
But now everyone is serious about building it, and there is no possibility of failure.
The principles are there, and the laws are there. All data is hard stuff. The only thing that can make it fail is accidents calculated by various people and not as good as God.
But Li Zhen felt that such an accident was unlikely to happen, because he found that the people at the Aviation Academy were a little perverted. The overall frame of the Grasshopper is made stronger than a car.
A wrist-thick steel pipe is the main beam of the Grasshopper, and thick wooden steel bars are directly welded to the main beam using mortise and tenon technology and support the wings. This skeleton alone probably weighs more than one hundred kilograms.
Fortunately, the Grasshopper is small in size, so no matter how heavy it is, it won't weigh much.
What surprised Li Zhen was that the wings of the Grasshopper were no longer hollow. There is starting to be padding in the wings.
It's a bubble.
The frame of the wing is filled with a layer of foam board and then covered with a layer of paper. Then covered with a layer of silk. And then there's the canvas.
Using foam will have no impact on weight, but will make the wing more stable.
Li Zhen looked at it twice and left. The Grasshopper will definitely succeed, so there is no need to worry about it. However, I am still a little relieved that the Aviation Academy has woken up and has not continued to expand.
Being able to go back and develop an aircraft like the Grasshopper from scratch shows that they are ready to be down-to-earth.
Also, what New Kyushu lacks now is flying experience. There is not only the pilot’s flying experience, but also the research and development experience.
People at the Aviation Institute didn't know that Li Zhen had come, and they just kept their heads down and continued to build the Grasshopper.
Although it is not technically difficult, it still needs to be taken seriously.
When the last layer of aluminum sheeting was applied to the fuselage, the Grasshopper was complete.
"Has the motoryard's engine been finished? Once it's done, let it be shipped over and put on it now."
Liu Jinghong gave the order, and someone immediately ran to contact the people at the Motor Vehicle Institute.
After a while, some people came over from the mobile hospital, and Ma Jianbin also came over curiously. It also brought a radial engine of the size of the Grasshopper.
Ma Jianbin looked up and down the Grasshopper, frowned and said, "Why is it so compact?"
Liu Jinghong rolled his eyes, directed the people to install the engine on the nose, and said, "This plane is short, but powerful."
Ma Jianbin smiled and said nothing. There was a trace of doubt in his eyes, could he fly at such a small size
How big was the previous Swordfish, and how big is this Grasshopper
Look how big the airship is
Liu Jinghong said: "Don't think it looks small, but its stability is actually beyond your imagination."
Ma Jianbin laughed and said: "It won't crash again, right? I'm a little scared, for fear that you will blame our motor vehicle institute and say that the engine is not good enough."
Liu Jinghong glanced at him: "I can tell you the truth, the Grasshopper is safer than a car."
"Haha, how is that possible?"
Ma Jianbin obviously didn't believe it. Are you kidding me, airplanes can be safer than cars
The plane has to fly into the sky. After flying into the sky, a small accident will lead to death without a burial place. As for cars, cars run on the ground and are more controllable.
Liu Jinghong obviously knew that Ma Jianbin definitely didn't understand the reason.
When we say that airplanes are safer than cars, we are talking about the probability of accidents. It's not about the severity of what happened.
Of course, a car accident will not easily result in death. Once the plane has an accident, it is a narrow escape.
But what Liu Jinghong was talking about was the stability of the Grasshopper. It was too stable and too strong. Short and sweet. Even if the engine stalls in the air, the plane will not crash.
The only factors that caused the Grasshopper to crash were the explosion of the fuel tank or the encounter with a tornado.
However, with the Grasshopper's short size and the power of its seven-cylinder engine, even if it encountered a tornado, it would probably be safe.
After the engine was installed, the Grasshopper was finally born.
People from the aviation institute painted it red, which makes it look more in line with the compact feel. Looking at it from a distance, the first thing that makes people think of it is not airplanes, but candy.
Compared with the sci-fi streamlined figure of the Swordfish. The Grasshopper is more like a toy.
The next day.
Laoshan is excited again. The Aviation Academy has developed another aircraft called Grasshopper. Just today, it will be tested at the airport again.
Everyone was stunned:
"It's only been a few days?"
"Isn't this too efficient? In just a few days, another new type of aircraft appeared?"
"It's too hasty. It's a plane. How can it be used for just a few days? It doesn't seem reliable at first glance."
"The last crash is still fresh in my mind, so the aviation institute must be too impatient."
: "..."
